Add timeout to wait for network controllers to appear when netbooting.
USB ethernet adapter initialization usually is delayed and
they're not available immidiately after autoconfiguration. So we need
to wait a bit before giving up

Tidy up the #include's.
Remove the (now) unused #define PMAP_SHPGPERPROC. (This should have
been removed in r239236.)

iterate lock.
This causes LORs and deadlocks as some code paths will have the com lock
held when calling ieee80211_iterate_nodes().
Here, the comlock isn't held during the node table and node iteration
locks; and the callback isn't called with any (extra) lock held.

"m_getjcl:invalid cluster type" that occurred some
time back with the igb driver. This happens often when
booting over the net. I believe the NIC hardware is left
in a warm state when handed over to the driver, and a stray
RX interrupt happens earlier than the code is prepared for
it to happen. This change was verified to fix the problem,
its kind of a bandaid... but it is similar to what was done
in the igb code.
1) It is not useful to call "devfs_clear_cdevpriv()" from
"d_close" callbacks, hence for example read, write, ioctl and
so on might be sleeping at the time of "d_close" being called
and then then freed private data can still be accessed.
Examples: dtrace, linux_compat, ksyms (all fixed by this patch)
2) In sys/dev/drm* there are some cases in which memory will
be freed twice, if open fails, first by code in the open
routine, secondly by the cdevpriv destructor. Move registration
of the cdevpriv to the end of the drm open routines.
3) devfs_clear_cdevpriv() is not called if the "d_open" callback
registered cdevpriv data and the "d_open" callback function
returned an error. Fix this.

"device_free_softc()" and "device_claim_softc()",
to allow USB serial drivers refcounting the softc.
These functions are used to grab the softc from
auto-free and to free the softc back to the correct
malloc type, respectivly.

* the descriptor ID, and
* the multi-buffer support that the EDMA chips support.
This is required for successful MAC transmission of multi-descriptor
frames. The MAC simply hangs if there are NULL buffers + 0 length pointers,
but the descriptor did have TxMore set.
This won't be done for the 11n aggregate path, as that will be modified
to use the newer API (ie, ath_hal_filltxdesc() and then set first|middle|
last_aggr), which will deprecate some of the current code.
TODO:
* Populate the numTxMaps field in the HAL, then make sure that's fetched
by the driver. Then I can undo that hack.
Tested:
* AR9380, AP mode, TX'ing non-aggregate 802.11n frames;
* AR9280, STA/AP mode, doing aggregate and non-aggregate traffic.
This is required to support > MCS15 as more than 32 bit rate entries are
suddenly available.
This is quite messy - instead of doing typecasts at each mask operation,
this should be migrated to use a macro and have that do the typecast.
r233822:
Remove useless and wrong piece of code in fdt_get_range() which i
overwrites passed phandle_t node. Modify debug printf in fdt_reg_to_rl()
to be consistent (that is, print start and end *virtual* addresses).
r230560:
Handle "ranges;"
Make fdt_reg_to_rl() responsible for mapping the device memory, instead
on just hoping that there's only one simplebus, and using fdt_immr_va as
the base VA.
r230315
Add a function to get the PA from range, instead of (ab)using
fdt_immr_pa, and use it for the UART driver
r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb
This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.
This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.
